Device non. OPERATING SNAP-SWITCHES,

Specification of Letters Patent.

Application filedAugustl l, 1917'. Serial No. 186,247.

' To all whom it'may concern Be it known that J oLEs D. BISCAYART andFERNAND GAILLETEAU, citizens of the United States, residing at Atlanta,in thecounty of Fulton and State of Georgia, have invented certain newand useful Improvements in'Devices for Operating Snap-Switches; and theydo hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, and to the letters and figures ofreference marked thereon,

which form apart of this specification.

This invention relates to new and useful improvements in attachments tobuttons of snap switches, afiording a convenient means for attachmentthereto and consists of a single cord operated device, having variousdetails of construction, combinations and arrangements of parts whichwill be hereinafter fully described, shown in the accompanying drawingsand then specifically defined in the appended claim.

The invention is illustrated in the accompanying drawings which, withthe letters of reference marked thereon, form a part of thisspecification and in which Figure 1 is a view in elevation showing theapplication of our invention to a switch button.

Fig. 2 is an elevation of the inner face of the device.

Fig. 3 is a cross sectional view on line 3--3 of Fig. 2.

Fig. 4 is a detailed view showing a slight modification of theinvention.

Reference now being had to the details 0 the drawings by letter:

the plate at right angles thereto to retain the weighted member Ebetween the flanges and in the position shown in the drawings. Saidplate has a circular outlined opening F formed therein, and H is aratchet wheel having a central raised circular outlined portion H whichis journaled in the said opening and lugs I are struck up from theflanges and are bent at right, angles thereto and serve to retain theratchet wheel within the opening forming a bearing therefor.

Said circular outlined raised portion of the ratchet wheel is providedwith an elongated slot, designated in the drawingsby letter K. andlL isthe button clutch member, bent substantially U shape andextendingthrough said slot. Said member L has laterally extending lugs L whichare bent at right angles at a point designated by letter L and passingthrough slots H formed in the circular outlined portion of the ratchetwheel and which serve to securely anchor the clutch member to theratchet wheel. Said ratchet wheel has laterally extending fingers 0parallel to each other and which fingers have angled lugs O projectingfrom the edges thereof and which are adapted to engage over the ends ofa switch button to securely anchor the clutch member to the button. Apawl, designated by letter T has pintles projecting therefrom which arepivotally mounted in a lug S integral with the flange ofthe plate and inan aperture in the latter, said pawl being adapted to engage the teethof the ratchet wheel. Said pawl, it will be noted, has a laterallyprojecting lug T guided in the slot A formed in the plate and whichserves to limit the outer throw of the pawl.

- In the modified form, shown in Fig. 4-. of

the drawings, it will be noted that instead PatentedApr. so, 1918.

moving in one direction and turns idly over the same when moving in theopposite direction, otherwise the modified form embodies the sameconstruction as disclosed in Fig. 2 of the drawings. Upon reference toFig.

4 of the drawings, it will be noted that the marginal edge of theopening in which the ratchet wheel is journaled, is designated by dottedlines, and that a space intervenes between the marginal edge of thestrucleup portion '11 and the circular dotted line and by reason of alateral or wabbling movement, which willbe imparted to the wheel as theratchet teeth come in contact with said pawl.

. a-tor, by pulling upon the cord, will cause the ratchet Wheel to begiven a partial rotary movement byythe. pawl, engaging the teeththereof, thus causing the button to turn. dWhen the cord is released,the weight will cause theplate to return to its normal position, thepawl turning idly over the ratchetwheel-.- 7

:What, we claim to be new is Anattaclnnent for turning switch buttons,comprising aplate havinga circular outlined opening therein, aweightedmember mounted upon one end of the plate, and

When r a cord connected to the plate at the end opposite the weightedmember, a ratchet wheel having a circular outlined struck up portionjournaled in the side opening, said ratchet wheel having an elongatedslot therein, a button clutch member engaging said slot and havingfingers for attachment to the button of a switch, means for fasteningsaid member to said wheel, a pawl pivotally mounted upon the plate andhaving a laterally extending lug movable in a slot in the plate.

In testimony whereof We hereunto afiix our signatures in presence of twowitnesses.
